As we enter the final days of the 2012 season, Detroit Tigers third baseman Miguel Cabrera is trying to do something no ballplayer has done in 45 years—win a Triple Crown. The last Triple Crown winner was Boston's Carl Yastrzemski, who led the American League in all three major batting categories in 1967.
